Importance of aerobic stability in silages

Abstract

Aerobic stability is a term that indicates the length of the time that silage remains cool and does not spoil after it is exposed to air. Therefore, rapid removal of air from forage mass and prevention of air infiltration into the silage during storage and feed out are the important factors that determine the duration of the silage aerobic stability. The measurement of CO2 production, separately or in combination with other measurements such as temperature, pH, lactic acid and volatile fatty acids and microbial examination, can serve as a reliable laboratory method to determine the duration of silages aerobic stability in silages. This paper work has aim to point on the importance of determination the duration of aerobic stability of silages, because quality changes and losses in the case of aerobic degradation.

Aerobna stabilnost je termin kojim se definiše dužina vremena za koje silaža ostaje hladna i ne kvari se po izlaganju vazduhu. Zbog toga, brzo otklanjanje vazduha iz silaže tokom siliranja i smanjeno izlaganje vazduhu po otvaranju silosa su dva važna faktora koji određuju dužinu aerobne stabilnosti silirane stočne hrane. U proceni aerobnog kvarenja,merenje proizvodnje CO2, odvojeno ili u kombinaciji sa drugim parametrima kao što je temperatura silaže, pH vrednost, sadržaj mlečne i sirćetne kiseline i mikrobiološka analiza, mogu se koristiti kao pouzdani laboratorijski metod. Ovaj rad ima za cilj da ukaže na značaj procene vremena trajanja aerobne stabilnosti stočne hrane,zbog promena i gubitaka kvaliteta pri aerobnoj degradaciji.
